Well, here are my thoughts from showing other breeds, and studying EM breed standards, watching hours of videos of EM classes, etc.
A couple of my breeders have also said that a puppy demonstrates its show potential (i.e., you can see what you are going to have at the end of the day) at 8 weeks and 8 mos. I do think the latter is not exact, though, because I have noticed some bloodlines grow and mature more slowly than others. My puppy Boris is almost 7 months, and is a sturdy little block, with a flat topline, deep chest, and a very nice head that has suddenly grown wider and deeper so that his muzzle length to occiput length is correct and overall is a nice square however you view it.
However, just last month, he was teeter-tottering (hindquarters high one week, shoulder high the next), very lanky and gangly, and his muzzle looked long and snipey. Having a 'humpy' back, or conversely a 'sway' back can often be due to the teeter-totter leg growth pattern. Boris and all of my Dane puppies had 'humpy backs' at least briefly
So looking at Kryten, first of all his colour is gorgeous! It definitely looks to me as if he is in a lanky, teeter-totter growth phase. It would obviously be helpful if you could stack him, as it does look like something might possibly be not quite correct in the slope of his bum, and the way he stands with his legs well under him. On the other hand, if his shoulders and front legs are a lot shorter at the moment, this may just be a comfortable way for him to balance himself. The depth of his chest in the side pictures, and the space between his front legs, do suggest (at least to my eye) that he will develop a nice chest.
His ear set looks quite nice -- extending the line of the top of his head -- and his head already has good depth, looking at his head from the side in the 2nd top picture. He has a good stop, and I think you will find his head is going to grow and broaden very soon, as Boris's did.
So all in all, I would say it's still a bit too soon to really evaluate him, but he has a potentially nice start.
